Inverted spin on this little guy is faster than you can count. Grab some altitude and initiate the inverted spin (down, left aileron and right rudder). As the spin develops slowly bring the elevator to neutral while holding the rudder and aileron...the rotational speed will increase. Neutralize to recover, it will take about 20 feet so leave at least 21 above the ground.
This is when the flaps come in handy: I put a 430ma 2 cell lipo in the Beast and it flew fine with lots of extra flying time. However with the extra weight the landing flare was encountering full stall. With full flaps during the final flare the landing works out great. There's only so much weight a flat wing will lift with low power. During flight the big 430 pack is not very noticeable though the snap rolls are better.
WhooHoo...AS3X System in the Beast! This already is a super acro plane in dead calm air but the 3 axis gyro damping AS3X System will really make a difference in turbulent conditions. At 2 oz., the Beast gets knocked around...even the difference between bright sun and shade can wiggle the wings. The Beast has the power to tackle fairly strong wind but precision acro is not possible because of heading diversions. Count me in on a AS3X receiver...fly by wire is here and I can't wait.
I replaced the elevator and rudder servo motors since they were running rough. Some used motors out of a BNF Sukhoi slipped right in. Pretty tiny wires but Radio Shack sells a small pointy soldering iron that was just right. Get some thin diameter solder while you're at the store. Just cut the tape on the cockpit section and cut the white silicone that holds the receiver to get it out. Delicate work but nothing difficult. The replaced servo motors run great. I'll get some new spares.
Flaperon setup continued: Once the receiver has split ailerons, one port is now channel 6 and one port is channel 2 for aileron. Set up the flaperon mix on the transmitter to whatever percent looks right. My JR transmitter has a landing flap switch so I set up 15 degrees for landing. Then I couple the retract switch with channel #6 for 40 degrees flap for final flare.
The Flaperons were simple to set up. A pro transmitter is required with flaperon option. The Beast receiver has two ports to work the ailerons and are shipped in aileron mode. Reprogram the receiver by turning on the transmitter and holding high throttle, down elevator and left aileron. Then plug in the Beast battery and let the receiver go through it's list of beeps and chirps as it sets up split ailerons. This takes about 15 seconds and be careful of the propeller at all times.
The UMX Beast is a hoot to fly and looks fantastic. The pro brushless setup is a dream come true for something this small. No brownouts, short flights or burned up motors. Flaperons help a lot for precise landings in small spaces. All maneuvers are possible and the Beast excels in knife edge and vertical rolls. This is a tiny airplane that weighs around 2 ounces so turbulence tosses it around some but in calm air it's very precise.
